Embodiment Construction
[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0037] The single and double angle steel transition node provided by the embodiment of the present invention is used for the connection between the single angle steel 1 and the double angle steel 2 arranged in the same direction in the angle steel tower of the transmission line, wherein the two angle steels in the double angle steel 2 are paired Corner cross stitching or T-stitching, such as Figures 4 to 9 As shown, the transition node includes connecting plate 3 and filling plate 4; the number of "L"-shaped connecting plate 3 is 2, and its two limbs are connected with the two perpendicular and adjacent single angle steel 1 and double angle steel 2 respectively. Limb connection, the angle between the two limbs of the single angle steel 1, the angle between the two limbs of the double angle steel 2 and the two limbs of t...

The invention provides a single-double angle steel transition node which is used for connection between a single rod of angle steel and double-spliced angle steel which are disposed in the same direction in an electric transmission line angle steel tower. The node is improved in that the node comprises connecting plates and filling plates, wherein the connecting plates are disposed between two limbs of the single rod of angle steel and the double-spliced angle steel which are mutually perpendicular and adjacent respectively; and the filling plates are disposed between the two limbs of the single rod of angle steel and the double-spliced angle iron which are mutually parallel and adjacent respectively. In comparison with the prior art, the single-double angle steel transmission node provided by the invention has the advantages that construction and layout are smooth and compact; the appearance is concise; a wind prevention area of the overall structure is reduced; external loads are reduced; force bearing performance of the overall structure is improved; construction technologies are simple; and production efficiency is greatly increased.
Description
technical field [0001] The invention relates to an angle steel transition node, in particular to a single and double angle steel transition node used in transmission line iron towers. Background technique [0002] In the design process of transmission line towers, especially for high-voltage tower structures with high loads or multiple circuits on the same tower, the internal force of the main material may exceed the bearing capacity of the existing largest single angle steel. [0003] In this case, it is necessary to splice two angle steels together, and the splicing method can be diagonal cross splicing or "T" splicing to meet the requirements of structural bearing capacity. Due to the force characteristics of the transmission tower, the upper part of the main material is less stressed, and the lower part is more stressed. The main material with a larger lower force needs to use double-joint combination angle steel, while the main material with a smaller upper force can us...
